ATTORNEY arnnr 1 COMBINED LETTER-SHEET AND ENVELOP.

Specification of Letters Patent.

Patented July 2'7, 1915.

Application filed January 24, 1914. Serial No. 814,250.

To all whom it may concern Be it known that I, WILLIAM G. CHAM- cans, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Combined Letter-Sheets and Envelops, of which. the following is a specification.

This invention relates to a combined letter sheet and envelop and has for its object to provide an article of this character comprising a sheet of paper provided with a window in the form of an opening through which the name of the addressee will be brought into view when folded and sealed for transmission and through which the name and address of the original sender may be exposed when replying to such communication. or on the return trip of said combined letter sheet and envelop.

Another object is to provide a combined letter sheet and envelop by which short communications can be exchanged without putting the addressee to the expense and inconvenience of furnishing paper and an envelop or the trouble of addressing the communication.

Another object is the provision of a combined letter sheet and envelop provided with a single opening or window through which the name and address of the original addressee and on its return trip the name and address of the original sender may be exposed, thus providing a larger space for the communication and rendering the article less expensive and more durable.

With these general objects in view the inventionconsists in certain novel and peculiar features of construction and organization as hereinafter described and pointed out in the appended claim, and in order that it may be fully understood reference is to be had to the accompanying drawing, in which- Figure 1, is an inside face view of the combined letter sheet and envelop ready to be folded to assume the form shown in Fig. 2. Fig. 2, is a fragmentary sectional perspective view of the combined letter sheet and envelop when folded to the form shown in Fig. 4 and ready to be forwarded by the original sender. Fig. 3, is a view similar to Fig. 2, the same-being taken on the line III-III of Fig. 4. Fig. 4:, is a perspective view of the combined letter sheet and envelop when ready for its return trip, with the name and addressee of the sender exposed through the opening or transparent portion.

In the said drawings, the combined letter sheet and envelop is shown as comprising a plurality of folding sections numbered 1, 2,

3, and 4. One of these sections, 2, is pro-- vided with a window or opening 5 through which the name and the address of the original addressee may be exposed, or on its return trip the name and address of the original sender. Two of the sections 1 and 2 are provided with gummed flaps or extensions 7 and 6 respectively, the gummed faces of said flaps or extensions being on the inner face of the letter sheet as shown by shaded lines in Fig. 1. The outer face of section 4 is adapted to have written or printed thereon the name and address of the sender of the letter so positioned that when the sheet is folded such name and address will be exposed through the opening 5. The communication from the sender is adapted to be placed on the inner face of section 3, and on the inner face of section 1, will be written the name and address of the addressee.

When the issuing oflice is ready to forward the letter, the flaps or extensions 7 are folded to inoperative position as shown in dotted lines Fig. 1, with their gummed faces upon. the inner face of sections. Said section 1 is then folded with its inner face against the inner face of section 2 to expose the address on said section through the window. Section 4: is then folded against section 3, and section 3 is folded to cause said section 4 to lie flatly against section 1. The flaps 6 of section 2 are then brought around the ends of the sections and upon the outer face of section 3, to which they are caused to adhere to seal the envelop, as shown in dotted lines, in Fig. 2. When this letter is received by the addressee it is opened by cutting or tearing off the flaps or extensions 6. When it is desired to use the letter sheet and envelop as a return trip letter and envelop, the recipient writes his communication on the inner face of section 4 and when ready to forward the same, opens out the gummed flaps or extensions 7. Section 4 is now folded upon section 3 and the latter upon section 2, so as to expose the written or printed name of the original sender through opening 2. Section 1 is then folded upon the outer face of section 3 and the flaps 7 are secured through their gummedsurfaces upon the outer face of section 2, as shown in Figs. 3 and 4. It will thus be seen that with this combined letter sheet and envelop the communications are securely sealed and that there is no danger of severing the flaps 7 upon its receipt by the one to whom it is first addressed. Furthermore by providing the letter sheet with a single opening or transparent portion, it is more durable and can be manufactured at less expense and being put to the expense of providing himself with paper and envelop. Furthermore he may write any communication desired, as 1t Wlll not be exposed to vlew 1n transm1s- I claim A letter sheet having four folding sec-.

tions, the two end sections being adapted to contain on their opposite sides the names of the sender and addressee, and one of said end sections having securing flaps or extensions and the adjacent intermediate section similar securing flaps or extensions and an address exposing window.

In testimony whereof, I affix my signature, in the presence of two witnesses.
